Question

Windows 11 experimental channel 26340.9750

So I updated to that experimental build and after logging in, I see just a grey screen with a white cursor. Tried fixing it with task manager but it just dosent work. My theory is that it’s a windows explorer exe crash and if it’s not fixed a soon as possible, I might stay off the insider channel by resetting my laptop using WinRE (windows recovery environment).

any other fixes I can try without losing all my data?

Sincerely,

Maria Sellali

Hi Maria,

File the issue in the Feedback Hub

using WIN+F.

Open Settings, Windows Update,

Update History, Uninstall Updates

and Uninstall the last one shown

If it fixes the issue, then Pause Updates

until the next build comes out.

The problem is that I can’t open settings. Even Feedback. The only things that work on the desktop are:

ctrl + shift + windows + b (already tried)

power button (already tried)

ctrl alt del (also tried):

singing out

emergency restart.

also tried to force explorer.exe using task manager, cmd. Also forcing to uninstall updates by cmd but still couldn’t because it still errors out
